Patented July it 92522.

Application filed December 21, 1910. Serial No; 598,589.

To all whom it may concern Be it known that I, Gnome I-L TOMLIN- son, a subject of the King of England, re siding at Chicago, in the county of Cook and State of Illinois, have invented a certain new and uset'ul Improvement in the Apparatus for Feeding Materials to Digesters, of which the following isa specification.

My invention relates to improvements in apparatus for feeding materials to a digester, and is illustrated diagrammatically in one form in the accompanying drawings, wherein- Figure 1 is a longitudinal sectional view of the. apparatus; Fig. 2 is a section along the line 22 ot Fig. 1; Fig. 3 is a section along the line 3-3 of Fig. 1; Fig. 4 is a detail ot'a modification.

Like parts are indicated by like letters throughout the several figures.

The belt conveyer. A. rides over the'pulley A in opposition to the scraper A which discharges onto the inclined weighing platform A. which is supported at the edge near the pulley by the knife-edge A on the bracket A and at the edge farthest removed therefrom by'thc knife-edge A and connecting link A which terminates at its upper end in the eye A carried by the hook A and supporting spring A which is carried in the bracket A adjustable in position on the guide A".

The weighing platform A discharges :ti'ito the osjllating inclined tray B which is locate; within and supported from the chute B by means of the links B and which is oscillated by the link 13" and pulley B driven by the belt 13" from the pulley A The chute B terminates at its lower extremity in the funnel C and discharge pipe C in opposition to ll18 1'li{ll1ll0l6 C in the d'igester C and contains the; spraying nozzles C in communication with the pipe C which is supplied from the reservoir 0". The link A is carried on the knife-edge D on one end of the scale beam D which is provided with the knife-edge D lin opposition to the bracket D.on the chute il and has the adjustable counterbalance weight D* and is in pivotal engagement. at one end with the piston rod l), piston, I) and dash pot D The tunnels E which are in opposition to the spray nozzles U and duachargc' by means of the flexible tubes E to the pipe E and reservoir C, are carried on the frame E which is supported at one end by the link E from the chute B and at the other end by the arm E which projects from the fulcrum ot the scale beam D and arciso located along the frame E that any downward movement of the frame will take them successively out of opposition to the spraying nozzles v In the modification su gested in Fig. 4, I have shown the supply pipe C controlled by the valve F which is operated by means of the lever'F and link F from the arm E", It will be evident that 'while'I have shown in my drawings an operative device still many changes might be made in the size; shape and arrangement of the parts without departing materially from the spirit of my invention.

The use and operation of my invention are as follows :.As the belt conveyer operates, the material carried by it discharges upon the inclined weighing platform, and owing to its inclination passes across it in a continuous sheet being discharged upon the upper end of the oscillating inclined trr down which it travels to the funnel at the end'of the chute and thence through the pipe into the digester. Suitable means not shown force a continuous stream of acid or other liquid through the spray nozzles; this stream being discharged into the tunnels in the position shown and. thence back to the supply reservoir. When the material is' passing across the weighing platform its weightdepresses the platformv and raises the scale beamthus rotatingthe arnrwhich projects from the beam. and thus carrying the tunnels back out of register witlf the spray nozzles so they discharge-onto the ma terial passing along the traybelowa The arrangement issuch that one nozzle after another comes into operation and for a slight quantity of material only a few of the nozzles will 0 erate'while for a large qua h tity which greatly depresses the scale, all of the nozzles will. be brought-into operation. The relation between the amount of-inate rial passing and the amount of, acid discharged thereon is controlledby auendjust 10'5 able spring and afco-unt'erbalanoe on the scale beam, the dash-pot being pIOVldGdlo;

prevent any violent changes in the supply owing to any local disturbance' of. the

- amount ot'cellulose being discharged 'across the weighing plattorm.
